Rulmeca Moving ahead. PRESCRIBED USE AND DESIGN CRITERIA The elements that determine the initial design of a roller conveyor are: - The dimensions of the packages to be conveyed (x-y). - The condition of the support base of the packages in contact with the rollers. - The weight and number of packages to be conveyed for each sector driven by the single Drive Roller. - The transfer speed. Roller pitch (or distance between rollers). For efficient transfer of the packages on a roller conveyor it is good practice for the packages to have a sufficiently rigid and flat contact surface (so-called “rollable”)...

Rulmeca Moving ahead. Each type of roller proposed by Rulmeca is characterized by a nominal capacity value. Refer to the roller section or to the “Rollers for internal conveying” catalogue. It is defined as: P1 = Nominal load pressing down on a roller [daN] Pc = Load capacity of a roller or capacity [daN] Pr = Weight of the rotating parts of a roller [daN] Pt = Total weight of a roller [daN] Pu = Weight of a package [daN] n = Number of rollers The distribution of the load on the rollers cannot be extrapolated from its average value. The camber values of loads of the same weight increase or decrease...

Rulmeca Moving ahead. PRESCRIBED USE AND DESIGN CRITERIA CHOOSING YOUR DRIVE ROLLER The conveyed material moves perpendicularly to the axis of the roller, so when calculating the necessary forces, the revolving friction of the roller with the surface of the base of the conveyed package must be taken into account. Apply this formula to define the tangential force necessary for handling the package: Ft = P x G x U where: Ft) required tangential force [N] P) Weight of the package (kg). G) Gravity acceleration = 9.81 [m/s²] U) Friction coefficient. Once the tangential force that is necessary to move...

PRESCRIBED USE AND DESIGN CRITERIA Rulmeca Moving ahead. POLY-V BELTS TABLE - Electrical conductivity < 7 MO. - Temperature range -20 to +90 °C. - Belts for low-temperature environments can be used (please specify in order). For packages around and above 50 daN, 3-rib belts should be used. The optimum pretensioning for belts supplied by Rulmeca is obtained by complying with the roller pitches prescribed in the table below for the different belt lengths. Transmission is calculated on the basis of the performance guaranteed by the manufacturer of the belts used. Poly-V belts are available immediately...

Rulmeca Moving ahead. THE RDR DRIVE ROLLER The Drive Roller can support both a load acting directly on it (a portion of the weight of the package pressing down on the Drive Roller and/or the load due to the tension of the conveyor belt), and convey loads distributed on the roller conveyor portion driven by the Drive Roller. Load capacity The load capacity (Pc) on the individual Drive Roller is 110 daN for length as 1000 mm and 50 daN for length from 1000 to 1500 mm. Please contact Rulmeca in case of higher load capacity needs. Conveyable loads The total load that can be conveyed by the rollers...
